Send a regular ResultReceiver instead of a subclass.

With unbundled chooser, apps can't load the subclass when unparceling,
but we don't actually need the subclass on that end. Parcel and unparcel
on this end ahead of time to get the vanilla ResultRecevier
representation to send.

Test: atest CtsSharesheetDeviceTest (with unbundled flag on)
